Riccardin D, a macrocyclic bisbibenzyl isolated from Chinese liverwort Dumortiera hirsute, has been proved to have inhibitory effect on biofilms formation of Candida albicans in in vitro study. Our present study aims to investigate the in vivo effect and mechanisms of riccardin D against C. albicans biofilms when used alone or in combination with clinical using antifungal agent fluconazole. XTT...

INTRODUCTION Numerous environmental factors influence the pathogenesis of Candida biofilms and an understanding of these is necessary for appropriate clinical management. AIMS To investigate the role of material type, pellicle and stage of biofilm development on the viability, bioactivity, virulence and structure of C. albicans biofilms. METHODS The surface roughness (SR) and surface free e...

PURPOSE Candida albicans (C. albicans) and Proteus species are causative agents in a variety of opportunistic nosocomial infections, and their ability to form biofilms is known to be a virulence factor. In this study, the influence of co-cultivation with Proteus vulgaris (P. vulgaris) and Proteus mirabilis (P. mirabilis) on C. albicans biofilm formation and its underlying mechanisms were examin...

Candida albicans causes superficial and life-threatening systemic infections. These are difficult to treat often due to drug resistance, particularly because C. albicans biofilms are inherently resistant to most antifungals. Sophorolipid (SL), a glycolipid biosurfactant, has been shown to have antimicrobial and anticancer properties. In this study, we investigated the effect of SL on C. albican...

Aluminum (Al) toxicity is a global issue that severely limits root growth in acidic soils. Isolation of suppressors of the Arabidopsis thaliana Al-hypersensitive mutant, als3-1, resulted in identification of a cell cycle checkpoint factor, ALUMINUM TOLERANT2 (ALT2), which monitors and responds to DNA damage. ALT2 is required for active stoppage of root growth after Al exposure, because alt2 los...

By screening for suppressors of the aluminum (Al) hypersensitive Arabidopsis thaliana mutant als3-1, it was found that mutational loss of the Arabidopsis DNA damage response transcription factor SUPPRESSOR OF GAMMA RESPONSE1 (SOG1) confers increased Al tolerance similar to the loss-of-function mutants for the cell cycle checkpoint genes ATAXIA TELANGIECTASIA AND RAD3 RELATED (ATR) and ALUMINUM ...

We have previously characterized Pir32, a Candia albicans cell wall protein that we found to be involved in filamentation, virulence, chitin deposition, and resistance to oxidative stress. Other than defining the cell shape, the cell wall is critical for the interaction with the surrounding environment and the point of contact and interaction with the host surface. In this study, we applied tan...

BACKGROUND Vulvovaginal candidiasis (VVC) is a common gynecological disease. Candida albicans is believed to be mainly implicated in VVC occurrence, the biofilm of which is one of the virulence factors responsible for resistance to traditional antifungal agents especially to fluconazole (FCZ). Quercetin (QCT) is a dietary flavonoid and has been demonstrated to be antifungal against C. albicans ...
